Hi guys,
This is my first post and also my first time repairing an amp. Please go easy
I'm taking a look at my band-mates fender 112. It has two burnt resistors (R75 & R76) which have almost burnt a hole on the top and on the bottom the pads and traces have lifted.
Can anyone please advise me on the best way to treat this and get the amp working again.
I alredy tried replacing the resistors using the bits of trace and pad still left there, and although the amp was better for a short while it still didn't work properly - the problem being that the volume would suddenly drop after 30 seconds or so of playing and become really distorted, then intermittently would go back up again....
If anyone can tell me why the resistors burnt in the first place and if there is anything else I should check (though all caps look fine) then I'm all ears! I'm here to learn
